Several fixes; a couple of fdget_pos()-related ones from Eric Biggers, prepend_name() fix (bug was reported by many people, Imre and Jan being the ones I'd been able to find addresses of), plus a series of fixes for bug found by Max Kellermann - missing checks for false negatives from __lookup_mnt() in fs/namei.c + switching mnt_hash to hlist, turning the races between __lookup_mnt() and hash modifications into false negatives from __lookup_mnt() (instead of hangs). Please, pull from the usual place - git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git for-linus Commit ID of that branch should be 7fc5aaa083922420e2dec5d985420cb5f959b1ce; diffs are the same as what sat there since last Sunday, commit messages got updated a bit. Should've propagated by now...
